TL;DR: In this article, a comprehensive review of the state-of-the-knowledge and the main advances made thus far in the sugarcane sector is presented, where the authors review the major environmental impacts of rapidly expanding sugarcANE plantations on the land use change and its competition with food production, as well as those associated with sugarcaine cultivation in Brazil.

TL;DR: In this article, the authors present a synthesis of available information on the magnitude of the main impacts of straw removal from sugarcane fields for bioenergy production and therefore represent an easily available resource to guide management decisions on the recommended amount of straw to be maintained on the field to take advantage of the agronomic, environmental, and industrial benefits.

TL;DR: In this article, the authors evaluate the modifications in soil carbon stocks resulting from the main processes involved in the changes of land use in Amazonia and Cerrado biomes, and show that the conversion of native vegetation to pasture can cause the soil to function either as a source or a sink of atmospheric CO2.

TL;DR: In this paper, the authors evaluate some of the main greenhouse gas sources related to agriculture and land use change, to present strategies to mitigate these emissions and to increase C sequestration in the soil-plant system, in three of Brazil's main biomes of Brazil.

TL;DR: In this paper, the authors evaluated the changes in C stocks, as well as the GHG fluxes (N 2 O and CH 4 ) during the process of conversion of Cerrado into agricultural land in the southwestern Amazon region, comparing no-tillage (NT) and conventional tillage (CT) systems.
